Serial No. 479,437.

This invention relates to a combined stopper and applicator. It isaimed to provide a novel construction permit ing the use of a flexible metal diaphragm as distinguished from one of rubber or the like so that continued use and the elements will not deteriorate and render the device useless. v

Another object is to provide a relatively large s' opper orthe like which will withstand considerable pressure and enable prac tical use to be made of screw threads as an attaching means between the same and a I container. J A further: object is to provide a construcas central vertical section;

Fig. 2 is an inverted plan view of the combined stopper and applicator; and Fig. 3 is a view. similar to Fig, 1 but taken through a modified form.

Referring specifically tothe device of Figs.

1 and 2, it comprises a body of bakelite 'or equivalent phenol condensation product which has a'groov'e at 11 defining a stopper 12 adapted to extend into the mouth of a conventional container as at 13. This also provides a depending flange 14 on the body which surrounds the -bottle-at the neck. In-

ter-engaging screw threads 15 are provided between such neck and stopper body 10.

A sealing gasket 16 may be interposed in the groove 11 so that an o il-proof or tight joint will be provided. The rela' ively large construction of the stopper and the fact that it is made of bakeliteenables a very firm grip to be had thereon and'the same to withstand tion wherein the stopper serves as a holder which may be contained in the bottle 13.

considerable pressure when necessary to effeet a tight joint.

' The upper surface of the body 10 is preferably dished as at 17 and disposed across the top of the body is a flexible metallic diaphragm 18, which diaphragm has a downwardly and inwardly extending and thus constricted attaching flange 19 which embraces the exterior of the body 10. The flangel9 is attached to the body when the latter is plastic so that an hermetic joint or bond between the same will result. Said diaphragm normally assumes the position shown in. the drawings and its inherent flexibility automatically restores it to thatposition after depression or flexure therefrom,

t The body 10 has a central bore or passageway as at 20 with which an applicator, shown in the form of a tube 21 communicates, such tube being for instance of bakelite or glass 70 and secured to the body 10 while the latter is plastic so that an hermetic joint or bond will result. j

Inthe use of the device the diaphragm 18 may be flexed vertically in order to depress the same and upon restoration to normal position, as shown in Fig.1, cause air to draw into the tube 21, a portion of the material The device when unscrewed from the bottle at 15 may be again engaged at the diaphragm 18 in order to flex the same and expel the contents of the applicator in successive drops.

A modified form of the invention is shown in Fig. 3 wherein an applicator 22 isused similar to that at 21 and secured in a bakelite body 23 while the latter is flexed. Such body 23 has a top or gripping portion 24 that is relatively wide with a metal diaphragm 25 similar to that at 18, hermetically secured thereto while the bakelite is in a plastic condition.

Thisbody 23 has a stopper 26- which extends into the neck or mouth of the bottle 27 and has screw-threaded engagement therewith as at 28.

In addition, a gasket 29 is removably ap-- plied tothe body 23, the same being dilatable and engaged in a groove 30 of the body. 100 Such gasket will extend partly into the neck of the container 27 and also across'the to thereof, as shown, in order to provide a doub e gasket or sealing effect.-

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

I claim:

1. A combined stopper and applicator device having a body, a metallic diaphragm secured thereto, and providing an air space be tween the same and the, body, and an applicator extending from the body arranged in communication with said space.

2. A combined stopper and applicator device having a body, a metallic diaphragm secured thereto, and providing an air space between the same and the body, and an applicator extending from the body arranged in communication with said space, said body having a stopper adaptedto extend into a container and having a flange outwardly thereof adapted to surround the neck of a container.

3. A combined stopper and applicator device having a body, a metallic diaphragm secured thereto, and providing an air space between the same and the body, and an applicator extending from the body arranged in communication with said space, said body havinga stopper adapted to extend into a container and having a flange outwardly thereof adapted to surround the neck of a container, said flange in its inner surface having screwthreads to engage corresponding screwthreads on the container.

4. A combined stopper and applicator device having a head of a phenol condensation product, a flexible disc held in hermetically bonded relation thereon by such product and an applicator extending from the body communicating with the interior thereof below the disc.

5. A combined stopper and applicator device having a head of a phenol condensation product, a flexible disc held in hermetically bonded relation thereon by such product and an applicator extending from the body communicating with the interior thereof below the disc, said disc having a depending flange surrounding the body and constricted below the upper portion of said body.

6. A combined stopper and applicator devicehaving a body provided with a stopper member to enter the mouth of a bottle, a relatively large gripping portion extending from the stopper and formed of a similar condensation product, said portion having a relatively large flexible diaphragm hermetically secured thereto by the product, and an applicator connected to the stopper and communicating with the space between the disc and gripping portion.
